Who would pay if the breeder had to pay for a C-section for the dam which is not cheap? This is why BYBs/commercial breeders should not breed. Many think it is so easy with few costs and they will get lots of pups to sell! I talked a few commercial breeders from bidding on Basenjis at the dog auctions-told them about the once a year going into season-pups not being available for sale until after Christmas, possible C-sections, and the not too large litters.
I had never heard of this problem in this pup until now. It sounds like a developmental problem in the womb not a genetic one. The health website she linked to was for humans not animals/dogs!
